How long does water stay cool
22616
We generally add ice cubes in our packs when we fill them up to make them stay cooler longer. Plain ole water will stay slightly cooler outside than if it was in a bottle but does get warm because of the sun and your body temperature in a few hours.

The hydration bladder and the pack itself is not insulated, so it is like having a water bottle inside a normal backpack. The bladder is in the main compartment which is up against your back.There is a little padding in between, but not that much. Water inside the hose in particular will get warm pretty much right away in sunny weather. Water inside the pack will generally stay cooler.

I have never had water in mine last more than an hour, within an hour its stay cool.

Varies. One example: about 97 degrees, water fresh out of the store fridge, stayed cold about 20 min, still cool just over an hour later, still refreshing enough 1.5 hrs later, and then I ran out and refilled. But - that's one of the reasons I bought me a small one like this one!

Your body heat and outside temp will affect mainly obviously and water temp to start with but probably 1/2 hour to an hour for cold.

You got to pack some ice in it if you want it to stay cool for more than one hr

It is not that simple. They may stay cold in a good cooler all day, on the table maybe an hour, but on a hot swollen joint maybe 15 minutes. You want cold packs to transfer heat quickly so that they cool things. A better question is how much heat can they absorb? I put it in a cheap cooler with a liter bottle of water that starts at room temp. The bottle of water cools to about 50 degrees after a couple of hours and lasts about 5 hours. Being segmented it has more surface area and transfers heat faster than a solid pack. The solid pack stays frozen longer, but the water does not get as cool. It is not that simple.

They are not supposed to "cool" the water. They will keep water cold (I add ice cubes) for a good 20 hours. Contigo says there is a lifetime warranty on them. Maybe you have a faulty one??? Contact Amazon if that's where you bought it.

It is all dependent on how hot your water is. With hot tap water, it stays *hot* for 30minutes or so. Then it is just warm.

Depending on how hot your water that you put in it is, anywhere from 20 to 30 minutes and it's still warm, then. Very nice product, we bought two of them. It's very malleable.

Not enough to keep you cool. Water collects in the float when in a pool, but just a small amount. Maybe an inch.

No, it stays cool because of the air! If it does get warm, just let the air out and put fresh cool air in.it, takes just 2 mins.

3-5 minutes if the water is boiling hot. Probably more like 5-7 minutes if the water is hot but not boiling, like if you had it in the thermos for a few hours.

Ours is used mainly in a garage with temps between 90-95 degrees. A full tank of water lasts about 4-5 hours. We love it. It's not like full air conditioning but it makes a HUGE difference.

It probably depends on it you put ice in it. My ice water keeps ice in it at least 6 hours. I never use it without ice so I hope I helped in some way. It also depends if it is in a hot environment. But it does have good insulation. :)

More than 3-4 hours. Havnt tested it for that but distilled water is super cheap to buy so isn't a concern.

That's a very subjective question. It depends on how cold the water is when you pour it into the bottle. Also depends on what's the temperature outside the bottle. If its freezing outside then the bottle will keep the water cold for hours/days. If its a 100 degrees outside don't expect the bottle to keep the water cold for more than 30 minutes. If you put the bottle in the oven that's heated that's another story. So where do you want to take this bottle?

It doesn't take long at all to cool. Once you wet it, it immediately starts cooling. Yes, it feels cold and the cold lasts for several hours or as long as it's wet. I used mine inside the house next to me for hotflashes and it was really cold. I haven't tried to use it outside yet though.

I tested the water streaming from the unit with an instant read thermometer and it was 195 degrees. In the cup it is several degrees cooler.

I think I keeps my water cold/ cool for several hours. Not ice cold but it does stay cool. It is quite large for Milk.

Right now the temperature where I live is 90 degrees and this tends to be desert-type country. I can water for about a week at the most in these conditions. Earlier in the season I could get almost 2 weeks.

My coffee starts to cool down about 30 minutes after I fill it. And that is literally just starting to cool. Stays warm for a couple of hours. I hope this helps
